Portable high-performance roughness measuring device with 14 different roughness parameters

SRTPro

The portable roughness tester SRTPro is a high-precision measuring device that impresses with its wide measuring range and excellent performance. It is ideally suited for measuring roughness on metallic and non-metallic surfaces. Particularly noteworthy is the side-mounted test stylus of the SRTPro, which enables precise measurements on inner surfaces of bores and in grooves. This innovative feature expands the range of applications and ensures the highest accuracy even in hard-to-reach areas.

Measurement principle

During the measurement process, the sensor is moved linearly along the probing path. The probe follows the profile of the probing path and moves up and down. These movements are converted into electrical signals, which are then amplified, filtered, and converted into digital values using an A/D converter. Based on these values, a mathematical representation of the profile is created using a microprocessor. Based on this representation, the Ra and Rz values (or Rq and Rt values) are then calculated according to the relevant standards and displayed on the screen.
